[0027] like Figure 4-5As shown, the utility model provides a technical solution for a release film unloading device for double-sided adhesive production: the winding mechanism 7 includes a driving motor 2 71 and a mounting rod 72, the output shaft of the driving motor 2 71 is fixedly connected to the rear end of the mounting rod 72, and the front end of the outer wall of the mounting rod 72 penetrates to the front side of the L-shaped frame plate 2 6, the front side of the outer wall of the mounting rod 72 is provided with a thread 73, the front end of the winding roller 8 is fixedly connected to an iron ring 81, the mounting assembly 9 includes a convex plate 91, and the interior of the convex plate 91 is provided with a thread groove 910 connected to the inside and outside, The threaded groove 910 on the convex plate 91 is screwed together with the thread 73 on the mounting rod 72 to limit the installation of the winding roller 8.

[0028] The working principle of the release film discharge device for double-sided adhesive production is described in detail below.

[0029] like Figure 1-5As shown, after use, first, the drive motor 1 31 and the drive motor 2 71 are electrically connected to the control switch 15, and the control switch 15 is connected to the external power supply, and the winding roller 8 is sleeved on the outer wall of the mounting rod 72, and then the thread groove 910 in the convex plate 91 is screwed with the thread 73 in the outer wall of the mounting rod 72, so that the magnetic ring 92 is magnetically sleeved on the outer wall of the iron ring 81 for fixation, and then the discharge roller 5 with the release film is placed between the two positioning mounting components 4, and the drive motor 1 31 is started, and the drive motor 1 31 drives the bidirectional screw 32 to rotate, so that the two mounting plates 41 are driven to move toward the middle at the same time through the threaded sleeve 42, so that the connecting sleeve rods at both ends of the discharge roller 5 are respectively inserted into the mounting sleeve 47, and at the same time, the upper and lower arc-shaped clamping plates 45 on the left and right sides are respectively expanded outward along the connecting groove 410 to squeeze the spring 44, so that the two upper and lower arc-shaped clamping plates 45 are respectively clamped on the upper and lower outer walls of the release film on the discharge roller 5, thereby fixing the two positioning mounting components 4. The positioning installation component 4 clamps and limits the feeding roller 5, and the arc-shaped clamping plate 45 positions the release film on the feeding roller 5, and then one end of the adhesive substrate is passed around the outer wall of the rotating roller 14, and passes through the two rubber sleeves 12 through the L-shaped frame plate 12, and then is wrapped around the outer periphery of the winding roller 8, and then one end of the release film is passed through the middle of the two rubber sleeves 12, and is similarly wound on the outer wall of the winding roller 8 and bonded with the adhesive substrate. Subsequently, the winding mechanism 7 is started to drive the winding roller 8 to rotate, so that the adhesive substrate and the release film are wound and bonded. During the winding process, the ball 46 on the inner wall of the arc-shaped clamping plate 45 rolls along the outer wall of the release film for positioning, and as the release film decreases, the elasticity of the spring 44 causes the slider in the arc-shaped clamping plate 45 to slide along the slide rod 43, continuously positioning the release film, avoiding the deviation of the release film during the winding process, and improving the production quality and efficiency of the double-sided adhesive.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
